2 Claims. (Cl. 30-40) This invention relates to an improved repeatingrazor of the magazine type, and more particularly to a repeating razorwherein the handle of the razor is hollow and forms a magazine forreceiving a cartridge of blades and the head is pivoted for movementfrom the shaving position to a position in which it is aligned with themagazine to receive a blade therefrom.

It is accordingly, an object of this invention to provide an improvedsafety razor of the type having a magazine for holding a supply ofblades.

It is a further object of my invention to provide an improved razorwherein the head may be pivoted from a position in which it is alignedwith a blade magazine to a shaving position in which the head extends atright angles to the handle and is positioned forwardly thereof.

It is a still further object of this invention to provide a magazinerazor having means to prevent accidental ejection of a blade from thehandle and in which means are provided to prevent ejection of a bladewhen the head is not aligned with the magazine.

It is another object of the invention to provide means for retaining ablade cartridge Within the magazine and to release same automaticallyfor removal therefrom after the last blade has been ejected from thecartridge.

It is a still further object of this invention to provide a razor havingmeans to prevent accidental jamming of the feed mechanism.

It is an additional object of this invention to provide an improvedrazor which is simple in operation, inexpensive to manufacture, andrugged in construction.

Further objects and advantages of the invention will become apparentfrom the following description and claims, and from the accompanyingdrawings, wherein:

Figure 11 is a cross sectional view of the razor, showingd the partsthereof in the process of changing a blade; an

Figure 12 is an exploded perspective view, partially in cross section,showing the parts of the blade inserting mechanism.

Referring now to the drawings wherein like numerals designate the sameparts throughout the several views, 11 designates generally a magazinewhich forms a handle for the razor head, generally designated at 12,supported at right angles to and forwardly of the handle 11 when in theposition shown in Figure 1. Head 12 comprises the guard member 13 havinga flange 14 formed with 80 a recess 15, as may be best seen in Figure 4.A clamp member 16 overlies the guard 13 and clampingly engages a blade17 which is retained in shaving position on the head by a detent 18supported on the spring finger 19 secured at the end remote from thedetent from the underside of the guard, as best shown in Figure 5.Detent 18 passes through an opening 21 aligned with an opening 22 in theblade 17 and is urged into said opening 22 in the blade by the action ofthe spring finger 19 when the head is in the position shown in Figure l,by means hereinafter to be described, and thus fixedly retains the bladein the head 12.

A flange 23 extends at right angles to the clamp 16 and is suitablyrecessed at 24 to receive a strut 25 pivoted to the flanges 23 at 26.Strut 25 is provided at the pivoted end thereof with a cam slot 27,concentric with the pivot 26, having a radius equal to the distance fromthe pivot 26 to the opening 28 in flange 23, and at the other end with aflange 29 received beneath the flange of the member 31, which issuitably secured to one end of the handle 11. Strut 25 is engaged by lug30 and is thus tiltably secured by flange 31.

A post 32 has a portion 33 thereof extending at right angles thereto andhinged by pin 35 to the member 34 supported on the face of the handleopposite member 31.

As may be best seen in Figure 2, the strut 25 is received between theflanges 14 and 23 within the recessed portions thereof, and the post 32engages the flange 14 and is pivoted thereto by a pintle 36 passingthrough the aligned openings 37 and 28 in the flanges 14 and 23,respectively. A leaf spring 41 secured to the post 32 has a bifurcatedend 42 which engages beneath the head 43 of the pintle 36 and serves toretain the members comprising the head 12 in frictional engagement.

By virtue of the structure heretofore described, the head may be pivotedabout the pintle 36, whereupon the strut 25 and post 32 willsimultaneously tilt by virtue of the eccentric pivot 26, from theangular position shown in Figure 1 to the position of Figure 5, whereinthe head 12 extends in alignment with the axis of the handle 11 and theblade parallels this axis, in which position a blade may be inserted, ashereinafter described. As may be best seen in Figure 3, when the head isin the dotted line position shown therein, the pintle 36 engages in thebottom of the arcuate slot 27 and the vertical edge of the post 32contacts the underside of guard member 13, as can best be seen in Figure7, and serves as a positive stop to align the head and the handle for apurpose which will become apparent hereinafter. It will be noted thatwhen the head is in the position shown in Figure 1, a lip 45 on the post32 engages the spring 19, thus urging the detent 18 into the slot 22 inthe blade 17, thus locking the blade in the head, whereas in theposition of Figure 5, the detent is withdrawn from the slot 22 againstthe bias of the spring 19 by virtue of the engagement of the rear end ofthe slot 22 of the blade 17 with the beveled rear edge of the detent 18as the blade 17 is urged from the head, thereby freeing the blade 17 forremoval. As may be best seen in Figure 8, a projection 46 formed on post32 engages in a recess 47 in the flange 14, thus releasably retainingthe head in the position shown, while a projection 48 engages in arecess (not shown) in the post 32 to releasably retain the head inshaving position.

Referring now to Figures 7 to 12, the handle 11, which forms themagazine for the reception of a cartridge of blades 53, is preferablyformed of square tubing and is closed at the end to which the head 12 issecured by a member 51 having an opening 52 forming a blade slot thereinaligned with the head in the loading position. The blade cartridge,designated at 53, comprises a channel shaped member having a truncatedcorner portion 54 and a flange 55, formed with an outwardly extendinglug 56, overlying the open side of the channel. An angle member 57 has aleg 58 thereof suitably secured to a leg of the channel 53 interiorlythereof, and a leg 59 extending in parallel spaced relation to theflange 55. Plates 60 and 60' close the respective ends of the cartridgesand serve to rigidify same and insure accurate alignment between theslot 52 and the top blade of the pac An intnrned guide lip 61 formed onthe leg 58 engages in the recesses 62 in a stack of blades 17 disposedwithin the cartridge, while an inturned lip 63 formed on the channel 53engages the recesses 64 in the other end of the stack of blades, thussecurely retaining the blades against displacement in the cartridge. Itwill be understood that the lips 61 and 63 have the ends thereofadjacent the flange S spaced therefrom to permit the uppermost blade ofthe stack to be slid endwise from the cartridge by means hereinafterdescribed. A blank 65 may be disposed between the uppermost blade 17 ofthe stack and the flange 55 so that all of the blades are engaged withlips 61 and 63, thus securing all of the blades in the cartridge topreserve the edges against damage during a handling prior to loading thecartridge in the magazine. The stack of blades is urged into engagementwith the flange 55 by an arcuate spring 66 secured to the cartridge andhaving :1 turned lip portion 67 at one end and an extending leg 68engaging beneath the stack at the other end. The flange 55 is formedwith a recess 69 overlying the end 67 of the spring 66 and a leaf spring71 secured at one end to the flan e 55 has fixed to the free end thereofa cam member 72 which extends inwardly of the cartridge through anopening 73 in the flange 55 and the notch 73 in the ejector 77 intoengagement with the uppermost blade 17 of the stack, thus urging the cam72 upwardly against the bias of spring 71.

A channel shaped blade e ector 74, having a cap 75 at one end thereof,has a leg 76 having the extending end 77, the edge thereof being adaptedto engage the end of a blade, and an extending tip 77' which serves tolimit sidewise movement of the blade as it is pushed ahead by the end 77of the ejector 74. It will be noted that the member 74 is formed with aU-bend at 78, so that the edge 79 protrudes above the leg 76. Tt will benoted that the aforementioned blank 65 is slightly shorter than theblades 17 so that its ends do not engage the lips 61 and 63, and iswider than the blades so that the blank 65 extends from side to sidewithin the cartridge 53. Furthermore the blank 65 has its corners cutaway, as shown at 65' (Figure 12) to provide clearance for the tip 77'of the ejector 77 and not engaging lips 61 and 63,-should the blank, foranv reason, be displaced endwise.

To assemble the cartridge 53 with the ejector 74, the free edge of theleg 76 is inserted under the upturned edge 56 of the flange 55 and overthe upper face of the blank 65, so that notch 73' of the leg 76 will beapproximately o posite the free end of spring 71. The cartridge 53 andthe ejector 77 are now pressed together and the cartridge will snap intolace in the ejector, while leg 76 pushes down the blank 65. to occupy aplace over the blank and beneath the flange 55. The truncated corner 54of the cartridge greatly faclitates this operation.

The assembled cartridge and ejector is then inserted into the magazinehandle 11 until the end of the cartridge engages the end wall 51 of themagazine, whereupon the ejector flange 77 will extend through the bladeslot 52, as shown in Figure l, in which position it effectively sealsthe slot. It will be noted that when the cartridge has been loaded inthe magazine, it is engaged at its forward end by the wedge members 83and 84, and is thus effectively and accurately positioned relative tothe blade slot 52, the ejector 74 being suitably recessed at 85 toaccommodate the wedge 83. It will be noted further, that the cam 72 willbias the leaf spring 71 into engagement with the forward end of thewedge 86, which is secured interiorly of the magazine and thuseflFectively will prevent withdrawal of the cartridge until such time asthe last blade is ejected from the cartridge, thus permitting the cam tomove inwardly under the bias of spring 71, forcing the spring from thewedge and permitting withdrawal of the cartridge. The corner 79 and thelip 56 engage the magazine and position the ejector and cartridgetherein.

If it is desired to insert a blade in the head, the head is pivoted tothe position shown in Figures 7 to 11, and the ejector is withdrawnuntil the stops 81 and 82 engage. In this position, blank 65, or theuppermost blade 17 in the magazine, as the case may be, will occupy theposition previously occupied by ejector 76. If the ejector is now pushedforward, the end 77 of the ejector will engage behind the blade and movethe blade, now free of the lips 61 and 63, through the blade slot 52,into the head 12, now aligned therewith.

When a new pack of blades has been inserted in the magazine, the firstoperation will be to eject the protec tive blank 65, and this is done asif it were one of the blades. In this case, the blank, as it is ejectedwill take the place of a blade in the head and it will be necessary toeject the next blade to dislodge the blank from the head. It should benoted here that when head 12 is turned to the position shown in Figure 7or 8, the strut 25 will force apart flanges 14 and 23, against the biasof spring 41, thus displacing guard 13 forwardly in relation with clamp16. When the new blade is fed into the head 12, it will slide with itsback edge very close to the inside face of flange 23 until it iscentered in the head. At this position, the detent 18 in guard 13 willbe slightly forward of slot 22 in the blade. But as the head is turnedto shaving position, the strut 25 will slide into the recessed portionsof the flanges 14 and 23, respectively, permitting said flanges to cometogether, urged by the action of spring 41. Guard 13, which now movesback under clamp 16, carries with it detent 18, which engages in slot 22of blade 17 as soon as they are aligned. If, for any reason, the newblade should get out of line as it is pushed into the head, it isevident that the detent, coming from the front, will engage its slot 22and carry the blade back to its correct position against the inside faceof flange 23. By this time, lip 45 of post 32 will be pressing againstspring 19 to hold detent 18 tightly in slot 22, locking the blade inlace.

p In order to prevent operation of the blade ejector when the head isnot in position to receive a blade, there is provided (see Figures 1 and4) a safety stop member 91 mounted on a spring member 92 secured to themagazine 11. The stop 91 has a face portion thereof which overlies aportion of the blade slot 52 and an arcuate cam shaped face whichterminates in a sharp edge which engages in a notch 84 (Figure 12) andthus prevents withdrawal of the ejector. When the head is pivoted to theloading position, the lower edge of clamp bar 16 engages the face 93 ofthe safety stop 91 and cams it outwardly, thus freeing the ejector forwithdrawal and clearing the blade slot. Should the ejector be withdrawnand the head thereafter moved from loading position, the stop 91 willobstruct the slot and prevent ejection of a blade.

On occasion, a blade may partly be ejected and the ejector thereafterwithdrawn. Should this occur, an attempt to eject the partially ejectedblade will result in engagement of the ejector with the end of the nextblade in the stack, and thus effectively jam the razor. My improvedrazor provides a push button 95 in the magazine 11, overlying theopening 69 in the magazine. The push button is normally held in theretracted position by a spring 96. Should the ejector jam in the mannerhereinabove described, depressing the push button will cause it toengage the rear end of the blade and depress the blade to a positionbelow the ejector 77, whereupon the ejector may be moved forwardly intoengagement with the partially ejected blade and complete the ejectionthereof.

While a specific embodiment of an improved magazine razor has beendisclosed in the foregoing description, it will be understood thatvarious modifications within the spirit of the invention may occur tothose skilled in the art. Therefore it is intended that no limitationsbe placed on the invention except as defined by the scope of theappended claims.

What is claimed is:

1. In a repeating razor, a magazine, a head pivotally mounted on saidmagazine for movement from a shaving position to a blade loadingposition, a cartridge within said magazine adapted to contain a stack ofblades therein, abutment means in said magazine, stop means engageablewith said abutment means for preventing the withdrawal of saidcartridge, and means responsive to the ejection of the last blade insaid cartridge for releasing said stop means.
